My student Mr. Tianyi Chen defended yesterday successfully his thesis titled as “Dense Subgraph Discovery: Novel Algorithms and Applications”. The committee was composed of Prof. George Kollios, Prof. Evimaria Terzi, and Dr. Atsushi Miyauchi. Tianyi focused on addressing dense subgraph discovery issues in contemporary graph datasets, including uncertain...

I had the honor to organize this year’s panel for the 10th IEEE International Conference on Data Science and Advanced Analytics (DSAA). While social media platforms have enabled global connectivity, empowering voices and democratizing information, they have also inadvertently become conduits for the spread of false narratives and misleading information....

Today, we are commemorating the 40th anniversary of the Computer Science department at Boston University and I had the honor to represent the data group as the speaker. Here’s a historical snapshot from the inaugural annual report (thanks to the department chair Abraham Matta), indicating the establishment of the Computer Science department. Steve Homer...

Mr. Kostas Sotiropoulos, my PhD advisee, has successfully defended his thesis “Methods, Algorithms and Impossibility Results for Machine Learning on Graphs”. Defending a PhD thesis requires extensive research, critical thinking, and the ability to present and defend one’s ideas in front of a committee of experts. It is an impressive accomplishment that...

Il Cattedrale di Santa Maria del Fiore in Florence is a masterpiece church. I read a story in John Kay’s book Obliquity [1] about the history of the dome that I find worth sharing with you here in case you don’t already know it. Filippo Brunelleschi was one of the architects competing for the commision […]

In CS131, we see the “Proof from the Book” due to Euclide that the number of prime numbers is infinite. Here is another favorite proof that is based on elementary facts. Suppose that is a list of all the primes. From what we have learnt about the  sum of geometric progressions we know that for […]
